The mutation of p53, a tumor suppressor gene, has been considered to play an important role in tumorigenesis in a variety of human cancers and the abnormal expression of p53 are frequently associated with poor prognosis. In order to examine the association of p53 overexpression with known prognostic factors including estrogen receptors (ER) and progesterone receptors (PR), we studied the status of p53 protein expression by immunohistochemical staining of paraffin sections of 29 endometrial carcinoma (25 endometrioid carcinoma, 2 clear cell carcinoma, and 2 serous carcinoma), obtained from hysterectomy. The results were as follows: The expression of p53, ER, and PR was present in 9/29 (31%), 3/29 (16%), and 12/29 (48%), respectively. The expression of p53 in endometrioid adenocarcinoma was present in 6/25 (24%) and showed significant correlation with histologic grade, nuclear grade, and myometrial invasion. The status of PR showed significant inverse correlation with histologic grade, nuclear grade and myometrial invasion. There was no significant correlation between ER status and these histologic factors. The expression of p53 was inversely associated with the status of PR, but statistically not significant. Our results indicate that p53 may be useful in predicting prognosis in endometrial carcinoma and will be able to provide helpful information in predetermination of aggressive behavior of the tumor in evaluation of curettage specimen.

The authors experienced two cases of cervical epidural AVM resembling that of tumor. It is the purpose of this report to point out by means of two cases the problem involved in establishing the diagnosis. To our knowledge, our two cases of cervical epidural AVM is the first report in Korea.

PURPOSE:The project of the neonatal mass screening test for inborn errors of metabolism are just at the beginning in Korea and there was a few reports about the overall incidence and subtypes of congenital hypothyroidism. METHODS:In this study, we analysed the 97 cases of newborns with hyperthyrotropinemia who were detected by neonatal screening test to identify the incidence and early clinical manifestations of each subtypes of congenital hypothyroidism. Thyroid function were measured by thyrotropin(TSH) level, T4, T3, Free T4, Free T3, thyroglobulin, T3 resin uptake, TBII, TBG in serum, thyroid ultrasonography and 99mTc thyroid scan. We reanalysed the thyroid functions 1 week after discontinuance of L-thyroxine treatment for 1 year. RESULTS: 1) The time of neonatal screening test were between 3 and 7 days after birth in 46 cases(47.4%) and 8 and 14 days after birth in 35 cases(36.1%). Two cases (2.1%) were done neonatal screening test at the age of 2 days old. 2) The major cause of thyroid disorders were primary hypothyroidism in 45 cases of the total due to thyroid aplasia(7 cases), thyroid hypoplasia(17 cases), ectopic thyroid gland(12 cases) and dyshormonogenesis(9 cases). Other causes of thyroid disorders were TBG deficiency(11 cases), TBG dysfuction(1 case), transient hyperthyrotropinemia(28 cases) and transient hypothyroidism(12 cases). 3) Serum level of thyrotropin(TSH) at diagnosis were 223.5+/-229.6microU/ml in thyroid aplasia, 41.6+/-42.9microU/ml in thyroid hypoplasia, 52.4+/-55.6microU/ml in ectopic thyroid gland. TSH levels were significantly high in thyroid aplasia. T4 levels in thyroid aplasia are 1.7+/-2.0microg/dl and this is significantly lower than other types of thyroid disorders. T3 levels were within normal range except in thyroid aplasia and TBG deficiency. 4) Prolongation of physiologic jaundice was the most common clinical manifestation(33.3%) in patients with primary hypothyroidism and macroglossia, hypothermia, umbilical hernia and cold skin were the next commom clinical manifestations in order to present. 5) Osseous development was normal in 57 cases(82.6%) out of 69 cases who accomplished roentgenographic examination of knees. Only 12 cases(17.4%) showed retardation of osseous development, but there was no significant differences between types of thyroid disorders. 6) Most of the newborn(93.3%) with primary hypothyroidism started to treatment within 8 weeks of age. 7) Initial dosage of L-thyroxine was 10microg/kg/day and decreased 6 to 12 months after treatment. 8) There was significantly decreased thyroid uptake of 99mTc after 1 year follow-up in 5 cases of dyshormonogenesis. 9) The serum TSH levels returned to normal ranges within 6 month after treatment in transient hypothyroidism and transient hyperthyrotropinemia. CONCLUSIONS:Special attention should be paid to transient hyperthyrotropinemia and transient hypothyroidism because many of the congenital thyroid disorders showed transient type and it is necessary to establish the diagnostic guideline to early detect these transient types of congenital thyroid disorders.

Anterior plate fixation of the cervical spine provides good primary stability to allow early mobilization without significant external support. Despite the obvious advantages of anterior cervical fixation, neurological injury resulting from the direct trauma of a drill bit or screw are possibile with this technique. In addition, screw loosening leading to dyphagia has been reported. The cervical spine locking plate (CSLP) system maintains the mechanical advantages of internal fixation and eliminate the neurological risks of perforating the posterior cortex. The purpose of this study is to review our experience with this device, to critically assess its ability to stabilize the cervical spine, and to assess for complications associated with this device. The authors reviewed 28 consecutive patients in whom the CSLP system was applied between April 1994 to April 1995. Average age was 44 years ranged from nineteen to seventy-two. Patients with trauma were eight and degenerative diseases were twenty. Eighteen screws were inserted in C3 bodies, twenty-four in C4, forty-one in C5, thirty-six in C6, twenty-four in C7, two in Tl and nine on grafted bone. With a mean follow-up of 15 months, 27 of 28 patients went on to fusion. Mean time to fusion was three months (range 2-5). Fusion status of one patient was considered as uncertain. Three patients had screws placed in the disc rather than in bone. One patient suffered deep wound infection, which developed to tracheoesophagial fistula. No patient showed neurological injury as a result of this device.

In the investigation of patients with internal disc disruption, a discography has been the best method to decide whether intervertebral disc is normal or abnormal. Magnetic resonance imaging (MRI) of the spine is a new technique which offers an alternative method of obtaining this information. Some authors have reported MRI was more accurate than discography, but other reports have indicated discography was more useful test in symptomatic lumbar disc disease. The authors performed retrospective study to evaluate the diagnostic value of the image findings of MRI and discography in the internal disc disruption. Image findings of MRI and discography were analyzed comparing to pattern of provocative pain during discography. The concordant pain at discography was considered as a gold standard for evaluation of the diagnostic value of these modalities. The image findings of MRI and discography for 60 discs of 21 patients were graded and compared with the pain response at discography. The validity and predictive value (PV) of these modalities were calculated and the correlation between these image findings was evaluated. The sensitivities of discography and MRI were 83.3% and 90.9% respectively. The specificities of these findings were 47.1% and 46.7%. The positive PV of discography and MRI were 52.6% and 55.6%, and the negative PV were 80% and 87.5% respectively. There was no statistical significance in these discrepancies. The determinations of symptomatic disc level based on image findings are unreliable. The MRI can be considered as a screening test for internal disc disruption since it is non-invasive and sensitive diagnostic tool. The fusion level should be decided by the pain pattern at discography.
